A proton is an elementary positively charged particle of an atom. It is a component present within all atomic nuclei. Protons are the lightest and most stable component of an atom. The numbers of protons in an element’s nucleus determine the atomic number of the element. This atomic number is the identifying characteristic of any element.
Protons are the positive charge within an atom that corresponds to electrons, which are negatively charged. Together, when in equal numbers, they neutralize a given atom and generate electrochemical stability.
